The Tech Garage Low Cost Borescope!

by Mike Kojima


Just a few short years ago having access to a borescope was a luxury that few racers, engine builders, and hobbyists could afford. You would typically have to spend a few thousand dollars for one. They were not that flexible, in that you would either not be able to record images or would have to spend a bunch of money for camera adapters. 

We had a borescope at work, and it cost something like $5000. It came in a large wood case that weighed 20 lbs. Not super portable.  The same for my buddies at Cosworth; they would have to lug the big borescope around to all the races and would bitch about it all the time if they were the ones chosen to take it.

Nowadays, a good borescope is still expensive, although there are inexpensive consumer grade ones for as low as $150 bucks. The borescope market is about to change. The Tech Garage has just come out with some very affordable borescopes that use your cell phone as the monitor. They start for as low as $19.95, and their high-end model costs only $69.95. 

How well do these borescopes work?  Let's see!


We tested out The Tech Garage's EE6000 wireless borescope, which is their top of the line model. The EE6000 connects to your phone via a wi-fi connection. 

The heart of the EE6000 is this tiny camera. Previously, borescopes would have an expensive fiber optic cable with a lens at the end going to a controller box.  The EE6000 uses cell phone-like technology to shrink a 2 megapixel HD camera with 1280x720p resolution into a tiny 8mm in diameter bullet. 

The camera has six LED lights around the lens that provide illumination in tight, dark places. The camera and its cable are waterproof.

This box is the camera control unit which has its own LED illuminator and the wireless wi-fi transmitter. It also contains the battery that powers everything and two micro USB ports- one for the charger and one for the camera.

Oh geez. I have one that is a bit older with its own dedicated screen and the like and it never worked particularly well... for $70, I'm going to have to pick this one up.

I have a very similar camera, but it is not wireless. It looks like it has the same small button box and potentiometer to take photos and adjust light, and bullet camera + led. Standard 10$ item on any chinese gadget online store.

And it also yields similarly scary images from pistons, like the "pitted piston" on page 2.

I was horrified when seeing this on all of my pistons. But then, once the head is removed ... "hey where are these pittings ?"

Yup, these are artifacts, so do not be alarmed.

iPhone and Android compatibility? Their website looks like a spam site, but maybe it's legit....hard to tell.

Croustl, did you see the eroded edges of the dish near the exhaust port?

They cost under $10 from china. I've had 2, the first one was dead on arrival and the second one broke within a day.

I got one of the chinese USB ones off eBay for £10, not as clear as this one but it saved my bacon big time. Working on a V10TT Audi RS6 and dropped a bolt down into the water pump housing, using the boroscope and a flexible magnet I managed to get it out without having to drop the engine and box out (a 20 odd hour job)
